Product Description:

Green Silicon Carbide

 

1.Introduction:

 

Green Silicon Carbide is an extremely hard (Knoop 2600 or Mohs 9.4) man made mineral that possesses high thermal conductivity (100 W/m-K). It also has high strength at elevated temperatures (at 1000°C, Green SiC is 7.5 times stronger than Al2O3). Green SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2815.5°C.

 

Green SiC is an entirely new batch composition made from Silica sand and coke, and is extremely pure. It can be manufactured in many complex bonded shapes, which are utilized for superrefractory purposes. Green SiC is also ideal for a wide variety of abrasive applications.

Q:What is refractory cement?
How to use exactly refractory cement? Someone professional advised me to buy this cement. Does it differ a lot from common cement? Is refractory cement expensive?
Q:How long is the duration of fire resistance that fireproof door of level B can endure?
According to the duration of fire resistance, fireproof doors can be divided into three levels, namely level A,B,C. And accordingly, the duration of fire resistance of them should not lower than 1.20h, 0.90h and 0.60h. Fireproof door, a door that can meet the requirements of fire resistance stability, fireproof door integrity and thermal insulation at a certain time, is a fireproof separator which is located in fireproof partition, emergency staircase and vertical silo. Apart from functioning as a common door, a fireproof can also prevent the spread of fire and smoke in a certain period to make sure that people are safely evacuated.
Q:What advantage and disadvantages it has compared to common fire insulation materials
Advantage and disadvantages of A-level heat perserving materials of equal effectiveness 1, the component materials of A level thermal insulation materials are inorganic materials, so it is high temperature resistant, non-combustible, fire-resistant; 2, good durability, aging resisitant, and having the same service life as buildings; 3, a level thermal insulation material can be well combined without using polymeride to bond, coat mortar, reinforced net, needing only few construction procedures. It is anti seepage with few quality problems; 4, absorb few water, and can bond firmly with the cement mortar, tile adhesive tile, safe and reliable; 5, a level thermal insulation material have the same service life as buildings, without the need to increase the cost on maintenance and renovation during its life span, and can maximize resource conservation.
Q:What's the refractory material?
Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.
Q:who knows the technology of fireproofing material?
1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
Q:What is the material of fire resistant glass reinforced plastics grating?
What is the material of fire resistant glass reinforced plastics grating?
Q:How should refractory cement be used?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will generate a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees.
Q:Could you tell me the fire-resisting time of class B fire proof door?
The fire-resisting time of class B fire proof door is 1h and thickness of door can't be lower than 45mm.
Q:What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
Q:How is the division of the fire resistant level of the rock wool board?
The fire rating of European style rock wool board is level A , which uses Da Guang Beijing Jinyu rock wool board, with the main advantages are: 1, High acidity coefficient: The high coefficient of acidity greatly improves the life resistance and weather resistance of the rock wool board. 2, Hydrophobic air permeability: According to the picture, Jinyu Star rock wool is water-repellent, at the same time it also has breathability, so the liquid water is not easy to dip into the rock wool, and the water vapor and other gas molecules could pass through the rock wool. In particular, the insulation materials have this feature which enables the building to have "respiratory function" thus making the room more comfortable and preventing anti-mildew phenomenon happening indoor. 3, Environmental protection: The goldfish can survive freely, which just shows it is environmental; 4, High strength: The advanced pleating and curing technology make the rock wool board tensile and high compressive strength. It not only can be applied on the external wall thermal insulation and sandwich board core material, but also can be used to make structural cotton in the flexible waterproof roofing. Its quality is so stable that it is convenient in construction and durable in use. 5, Fireproofing: Not just talking about the fire rating, but the fireproofing time, which is generally up to two hours, and can be used for lining thermal insulation fire-resistant part of the glass curtain wall, through-wall pipe seal, pier between two windows, window sill wall and other parts; 6, Derived advantages: Agriculture applies the soilless cultivation cotton;
